Went to Pitt River Hot Springs 2 weeks ago and the water was flowing into both hot spring pools.
Definitely in the morning it was ice cold down there. Which was unfortunate after going all the way out there....
Bottom pool was completely covered and the top one had significant spillage at times.
Beautiful location but kind of a gong show on the weekend. We counted at least 20 people heading in there on Saturday afternoon, along with multiple noisy jet-boats heading up the river all day.
